On the plus side, I got to see first-hand how Postgres handles deadlocks and read up on how to avoid them.

"I was wondering if you could go over the details of the resolution we discussed on DATE? I'm giving it consideration and just want to make sure I fully understand. On reflection I feel like it could be a great opportunity. Could I put it on my resume'?"

Sometimes they stitch themselves up and it's glorious when it happens.

They weren't milking it for attention. At EMF - at least early on - they were deliberately downplaying it to avoid causing a panic until the risk was known. Unfortunately when Atomicmaya's toot[1] dropped, they felt like they had to respond to squash any potential speculation or rumours. (the fear was someone would hear "orphan source" or "nuclear material" and think "Goiana incident, repeat of" -- Goiana was a much stronger caesium-137 gamma source).

Photos of the unit were being circulated privately in case there were more (the donator's identity was unknown at this point). EMF later announced in closing -- and you can see this on the recording [4] -- that they'd like to know if there were only two.

I've done basic risk assessment in a volunteer role and when there were unknowns, we took the path of assuming the worst, and planning for the best until we had more information. I can't really judge Tryst or anyone else for doing the same. In this case the worst-case scenario was a kid or teen at the camp buying it and taking it apart in their tent, and making the source material airborne.

Several people in the Furry Village google were trying to find information on the MIC based on the photos, and at the time we all found nothing.

The thing also very industrial which probably amped up the risk profile a bit further in peoples' minds, because it wasn't an obvious, recognisable, smoke detector.

This evening I googled the part number and sure enough, it's a very spicy (compared to modern ionisation detectors, about 10x the amount of Am241) early-generation smoke detector, and the Am241 is encased in gold. [2] [3]

TLDR: It's low risk, but that wasn't known at the time.

As LeoPanthera said above, Bell's exchange for the ability to make PCs was a bit of a bad swap in retrospect. It's pretty easy to see they were going for some kind of convergence of computing and telecoms (the 3B1 has an internal 1200 Baud modem) but they didn't do well on that bet.

UNIX software in general seems pretty thin on the ground. The OSes are out there (even rarities like Interactive Unix 4.1 - though not the later patches e.g. FDISK 2GB) but software? Hen's teeth.

ACCELL Unify would be interesting to find, it's the software General Instrument used to write the front-end for their cable TV headends.

I have a 7300 and a 3B1 (7300 is single half-height hard drives, 3B1 is two HH or one full-height). One has a Combo Card (RAM and serial) and a Floppy Tape card, I can't remember what the other has, but cards have been pretty thin on the ground. A DOS-73 or network card would be extremely nice to have.

The emulator actually started life because I couldn't find a machine for sale at a price I could afford, but the manuals were on Bitsavers. Someone later sold me the 7300 and 3B1.

Technically it is, if you mean System V for MC68k :)

AT&T rebranded it, and there were two versions: the 7300 can take a single half-height MFM drive, and the 3B1 can take two half-height MFM drives or a single full-height. The 3B1 has a different plastic case with a square-ish 'bump' under the monitor, and usually a modified (called a P5.1) motherboard.

They top out at 4MB RAM (2MB on the motherboard and 2MB on expansion cards). Disk storage would have topped out at 190MB with a single Maxtor XT-2190 full-height, or a pair of Miniscribe 3650s for 2x50 = 100MB.

Allegedly he'd quit three times in one year: https://lists.vcfed.org/pipermail/vcf-midatlantic/2019-Decem...

I dunno, the whole damn situation stinks, but it feels like there's a hell of a lot more going on here than just a box of magazines.

I don't really have the time to look into this more, it's not my group. My involvement was to reply as (I thought) a friend to ask both sides to chill and get around a table, and the outcome of that was that Jason opted to berate and belittle me. We'd worked together in the past (long time ago) on a preservation project and over time he's burned bridges with a lot of the people who worked on that.

I have no idea what's going on with Jason these days, but I hope he's okay.
